The answer will vary, for a start, depending on whether you believe in God or not... My opinion as a believer is that yes, God must somehow have caused the entire Universe to come into existence. It is hard to imagine a Universe that "made itself", or just sprung into existence without a reason, out of sheer nothingness. But HOW God made the Universe, we don't know in detail. And it would still be interesting to know more about his methods, i.e., how the Big Bang happened, and what came before it. Scientifically, this is difficult to answer; everything we see from the past of our Universe happened AFTER the Big Bang.
No. It is unknown what exactly 'caused' the Big Bang, but it cannot be explained by two atoms coming together.
No. If the theory is correct, then the big bang caused atoms.
Bang Bang Bang was created on 2010-07-09.
Bang Bang Machine was created in 1989.
No atoms did not create earth. Everything is made of atoms and the big bang create the universe which made a nebula and created the sun and the asteroids built up to form a large asteroid and made its own gravity which made the earth circular. That created earth.
Bang Bang Lulu was created in 1986-06.
Molecules did not exist at the time of the Big Bang and not even in the immediate time after. To make molecules one needs atoms but it took about 370.000 years after the Big Bang for the temperature had dropped enough for atoms to be stable.

Scientists "speculate" that the Big Bang created antimatter, but it was destroyed when coming into contact with stars, planets, and other matter.

Earth was created as a result of the big bang. Debris from rocks, dust and ice as a result of the bang were squeezed together by gravity, forming spherical planets.
